i recently upgraded my old Nvidia Geforce GTS 250 to a Nvidia Geforce GTX 580 so that i could play skyrim. but know i cannot play oblivion anymore i cannot see a thing after i load my savegame but i can hear everything that happens. its like there is a 100% fog everywhere. i know this is probably because my graphics card isn't supported anymore, but is there any way to make it work? thanks for the help in advance.
